We have own ring die factory and technical engineers with 20 year's experience. Each year, we all sell about 4000 spare parts: ring dies, rollers, roller assemblies to all over the world.Ring die is very important part of ring die pellet machine in the whole manufacturing process. The quality of ring die not only directly relates with the quality and output of pellets, but also the running state of equipment and maintenance cost.

Generally speaking, the higher the compression ratio, the denser the finished pellets. But it does not mean that the higher the compression ratio, the better the pellet quality.Compression ratio should be calculated based on raw material for making pellets and type of feed.With many years pellet die manufacturing and research experience of WEIFENG Company, we provide some general data of ring die's compression ratio for your reference:

Buyers can customize dies with different hole diameter and compression ratio, according to different situation and requirement.
